Abstract
An optical data transmission system includes an optical stack 10 of internally reflective chambers 20, each having ports 21 in which light emitters 15 and detectors 16 are arranged. These are mounted on the edges 13 of circuit packs 11 and 12 arrayed around optical stack 10 so that data can flow between the circuit packs by means of light pulses from emitters 15 irradiating the chambers and being detected by detectors 16. A processor controls which of the circuit packs transmit and which of the circuit packs receive so that the optical data transmission is not only fast but readily varied.
